Indian state assembly constituencies shapefile - pre-1976 delimitation

[Rohit James]

Hello everyone,

I'm looking for maps of Indian state assembly constituency boundaries (preferably, a GIS shapefile) prior to the Third Delimitation Commission (1976) i.e., assembly constituency boundaries as they existed in 1950s, 1960s and the early 1970s.

Any leads would be appreciated!

Thanks,

Rohit

Hi Rohit,

Were you able to find this? I am looking for similar data - shapefiles for each of the parliamentary elections prior to 2009 delimitation.
